The Navy began procuring Arleigh Burke (DDG-51) class destroyers, also known as Aegis destroyers, in FY1985, and a total of 82 have been procured through FY2019. The Navy’s proposed FY2020 budget requests funding for the procurement of three more DDG-51s, which would be the 83rd, 84th, and 85th ships in the class.
DDG-51s planned for procurement in FY2018-FY2022 are being procured under a multiyear procurement (MYP) contract that Congress approved as part of its action on the Navy’s FY2018 budget. DDG-51s procured in FY2017 and subsequent years are being built to a new design (the Flight III DDG-51 design), which incorporates a new and more capable radar called the Air and Missile Defense Radar (AMDR) or SPY-6 radar.
The Navy procured DDG-51s from FY1985 through FY2005, and resumed procuring them in FY2010. In FY2007-FY2009, during the time when the Navy was not procuring DDG-51s, the Navy procured three Zumwalt (DDG-1000) class destroyers. The Navy plans no further procurement of DDG-1000s.
